- Compare this experience with estimating a patient’s effective/organ dose for diagnostic exposures. What are the key differences and similarities in the approaches and the factors influencing the dose estimates? What practices in dose estimation have you assimilated by comparing these experiences?
- Revisit your calculations and any reflections made at the time. Have you gained a better understanding of the limitations and uncertainties associated with skin dose estimation in interventional procedures through subsequent learning? What would you do differently now?
- Discuss your approach and findings with experienced colleagues or your training officer. Have they offered insights into best practices or common pitfalls in skin dose estimation for these complex procedures?
